User-Context Tracking
The user context can now be tracked with FDA and therefore see which user made changes to a table.
Use DBMS_FLASHBACK_ARCHIVE.SET_CONTEXT_LEVEL procedure to do this …
ALL : All contexts from the SYS_CONTEXT function are stored. TYPICAL : Only basic auditing attributes from the USERENV context are stored. NONE : No context information is stored. EXEC DBMS_FLASHBACK_ARCHIVE.SET_CONTEXT_LEVEL('TYPICAL');
Use DBMS_FLASHBACK_ARCHIVE.GET_SYS_CONTEXT function to retrieve the data …
SELECT DBMS_FLASHBACK_ARCHIVE.GET_SYS_CONTEXT(versions_xid, 'USERENV','SESSION_USER') FROM FDA_TABLE VERSIONS BETWEEN TIMESTAMP SYSTIMESTAMP - 1 AND SYSTIMESTAMP;
Database Hardening
You can now group a set of tables in a Flashback Archive. These tables are known as Applications.
Create Application …
BEGIN DBMS_FLASHBACK_ARCHIVE.REGISTER_APPLICATION( application_name => 'DUBETECH_APP', flashback_archive_name => 'DUBETECH_FDA'); END;
Add Tables to Application …
BEGIN DBMS_FLASHBACK_ARCHIVE.ADD_TABLE_TO_APPLICATION ( application_name => 'DUBETECH_APP', table_name => 'CUSTOMERS', schema_name => 'DUBETECH'); END;
